Last year, Vodafone exited the Japanese mobile market to much fanfare when it sold its Vodafone K. K. to Softbank. It only took U.S. mobile firm NextWave Wireless one month to decide to sell its recently purchased stake in Japanese firm IP Mobile because the chances of making a profit in the tight Japanese market were slim.

The stake is 69.23 percent of IP Mobile.
